Thank you for the reply. In the mean time time, the way we got it to work was to insert unused 'dummy' containers as tabs, and then re-parent the desired control into those tabs upon a selection event.
So as of swt ~4.6 code like this will work: https://bugs.eclipse.org/bugs/attachment.cgi?id=250471 Thank you Leo Ufimtsev | Intern Software Engineer @ Eclipse Team ----- Original Message ----- From: "Gergely Polonkai" <gerg...@polonkai.eu> To: "Leo Ufimtsev" <lufim...@redhat.com> Cc: "gtk-app" <gtk-app-devel-list@gnome.org> Sent: Monday, February 9, 2015 12:36:18 PM Subject: Re: GTK, can GtkNotebook have a single control and all tabs pointing to it? Hello, I'm afraid this is not possible to do it this way; you will have to create some kind of wrapper widget. I would go on with GtkStack, and for the tabs themselves you may take a look into GtkStackSwitcher's source code.

In swt, some developers like to create a GtkNotebook (TabFolder) with many tabs but all pointing to the same control. (sigh, odd, I know...) The control is a viewer, and changing tabs changes the content of the viewer. However, in gtk I haven't been able to make this work. If I add the same child twice, it gives me warnings and errors: gtk_notebook_append_page (GTK_NOTEBOOK (notebook), child1, label1); gtk_notebook_append_page (GTK_NOTEBOOK (notebook), child1, label2); Warning: (gtk3_testing:17322): Gtk-WARNING **: Can't set a parent on widget which has a parent Theoretically speaking, can a GtkNotebook have tabs that all point to the same control? (and we just listen to tab-changing events)? Or is this impossible by principle of widget-hierarchy?
